What's new in plac 0.7http://www.artima.com/weblogs/viewpost.jsp?thread=301632
plac is much more than a command-line arguments parser. You can use it to implement interactive interpreters (both on a local machine on a remote server) as well as batch interpreters. It features a doctest-like mode, the ability to launch commands in parallel, and more. And it is easy to use too!
Threads, processes and concurrency in Python: some thoughtshttp://www.artima.com/weblogs/viewpost.jsp?thread=299551
Removing the hype around the multicore (non) revolution and some (hopefully) sensible comment about threads ad other forms of concurrency.
plac, the easiest command line arguments parser in the Python worldhttp://www.artima.com/weblogs/viewpost.jsp?thread=294291
Announcing the first public release of plac, a declarative command line arguments parser designed for simplicity and concision.

The EuroPython conference will be held in Birmingham UK, 19th to 22nd July 2010.
The wonders of cooperative inheritance, or using super in Python 3http://www.artima.com/weblogs/viewpost.jsp?thread=281127
This essay is intended for Python programmers wanting to understand the concept of cooperative inheritance and the usage of super. It does not require any previous reading. The target is Python 3.0, since it has a nicer syntax for super, even if most of what I say here can be backported down to Python 2.2.
Clearing cacheshttp://www.artima.com/weblogs/viewpost.jsp?thread=274438
A short note about a task I am doing at my day job, involving making sure that different caches are cleared consistently. For people wondering about real-life use cases of metaprogramming techniques.
Interfaces vs Inheritance (or, watch out for Go!)http://www.artima.com/weblogs/viewpost.jsp?thread=274019
Some musings about my personal history with inheritance and interfaces, solicited by the release of the Go language this week.
Managing Records in Python (Part 1 of 3)http://www.artima.com/weblogs/viewpost.jsp?thread=236637
This is the updated translation of a beginner-level paper I wrote for Stacktrace one year ago (see http://stacktrace.it/articoli/2008/05/gestione-dei-record-python-1/).
It basically discusses Python 2.6 namedtuples (plus some musing of mine).

What I am doing nowhttp://www.artima.com/weblogs/viewpost.jsp?thread=265857
This summer I have been quite silent on Artima. Here is an
update of what I have done and what I plan to do in the future.
The Adventures of a Pythonista in Schemeland/30http://www.artima.com/weblogs/viewpost.jsp?thread=261364
What does it mean that two identifiers are equal in a lexically scoped language with hygienic macros? This last
episode of part V tries to answer the question, by discussing three different concepts of identifier equality.
The Adventures of a Pythonista in Schemeland/29http://www.artima.com/weblogs/viewpost.jsp?thread=261363
In this episode I explain how to break hygiene in Scheme macros by using datum-&gt;syntax. I discuss how you can play
with the lexical context. Finally, I spend some word on non-hygienic macro systems versus hygienic systems.
The Adventures of a Pythonista in Schemeland/28http://www.artima.com/weblogs/viewpost.jsp?thread=260195
If there is a topic which is likely to engender a flame war between Schemers and Lispers, that topic is hygienic macros.
It is the time to face it, and to explain what people mean when they allude to the &quot;hygiene problem&quot;.
The Adventures of a Pythonista in Schemeland/27http://www.artima.com/weblogs/viewpost.jsp?thread=260182
In the last dozen episodes I have defined plenty of macros, but I have not really explained what macros are and how they work. This episode closes the gap: it explains the true meaning of Scheme macros by introducing the concepts of syntax object and of transformer over syntax objects.
The Adventures of a Pythonista in Schemeland/26http://www.artima.com/weblogs/viewpost.jsp?thread=259977
In this episode I add another item to the macro programmer toolkit (macros taking macros as arguments) and I bring an argument in favor of good old parentheses.
